Block Blast Solver: Free Online Puzzle Solver

Take a clear screenshot of your board and pieces, then upload it to get a suggested move.

A good move fits your board now and still leaves room for what comes next.

Snap a photo of your board, or type it in by hand when a screenshot is not an option.

Block Blast runs on a standard 8x8 grid, available on iOS and Android through the Google Play Store and Apple App Store.

After you upload, the tool detects the main grid and your upcoming blocks, then shows you what it found so you can check it. A clear screenshot gives this step a better starting point, since a blocked corner or a glare can hide a cell.

A useful comparison weighs line clears, open space, and piece fit together. A placement that scores less but keeps two extra cells open can beat one that scores more and closes them off.

A move that clears three lines can still box you in if it eats the last wide open area on the board. A smaller move that keeps space open often wins in the long run, since it leaves room for whatever piece comes next.

Tap one of the three blocks at the bottom of the board to pick it up.

Tap an open spot on the 8x8 grid where the whole block fits.

Fill a full row or column to clear it. The round ends when none of your blocks fit anywhere.

Players drop pieces into open cells on an 8x8 board. The Google Play listing describes this same setup, placing blocks and clearing full rows and columns as the pieces fill in.

A full row or column clears right away and opens up space for your next piece. Clearing more than one line in the same move opens more space at once, but it only helps if the board still works afterward.

Line clears add to your score, and clearing lines back to back builds a combo. Scoring can shift a bit between game updates, so treat any specific number as a guide rather than a fixed rule. Our Combo Strategy guide covers when a streak is worth protecting.

A run ends when none of your pieces fit anywhere on the board. That is why open space matters as much as points, since a full grid with no gaps left is a dead end no matter how high the score got there.

A clear feels good, but check what your board looks like right after. If it leaves a narrow gap that only one piece shape can fill, it may cost you more than it earns.

Big or odd shaped pieces need room. Keep a few open zones ready for them instead of spreading small gaps across the whole board.

A tiny gap can sit empty for turns if nothing fits it later. Two or three connected empty cells can take more piece shapes than the same number scattered apart.

Do not judge one piece alone. The pieces next to it can change your best move, since a placement that looks fine on its own can block the only spot the next piece needs.

The same three pieces can leave very different boards depending on which one goes down first. Placing the hardest piece early, while more space is open, is a small hack that can help keep a board alive longer.

Any solving algorithm needs an accurate picture of the board first. If the grid is read wrong, every suggestion built on it can be wrong too.

A move that looks fine on its own can still be the weaker choice once you compare it with the other legal options on the board.

A clear can open real space or barely help at all. That difference matters, especially late in a run when every open cell counts toward your next few turns.

Open space adds flexibility, even on a move that scores less right now. A wide gap that fits several piece shapes can be worth more than a few extra points today.

Your first move should not box in the pieces waiting behind it. The best placement right now is the one that still leaves a fair shot at placing what comes next.

A blurry photo, a hidden corner, or a misread piece can throw off the result. A heavy glare or a notification banner across the top can cause it too.

Compare the detected board to your screen. Fix anything that does not match before you move, since one wrong cell can change which placement actually makes sense.

No tool can promise a win on every board. Some positions run out of legal moves no matter what, and that outcome reflects the board itself, not a flaw in the check.

Classic mode is the core loop. Place pieces, clear lines, and push for a higher score.

Adventure mode adds progressive levels with their own designs and themes. Details can shift with game updates.

The same placement skills carry over. The goal in front of you just looks different. Our Classic vs Adventure Mode guide compares them side by side.

What matters is whether your board matches the format the tool reads. Check the detected board either way.

Look at every piece you have left. Find one that clears a line and still leaves room behind it.

This means none of your pieces have a legal placement left on the board. Earlier moves likely narrowed your space more than it looked at the time. Our No Moves Left guide explains what to do next.

No. Some boards run out of legal moves no matter how well you played.

Yes. A solver reads your board and suggests a placement. What you do with that suggestion is your call. Our Block Blast cheat guide covers the difference in more detail.

Use a clear photo that shows the full board and every open piece.

Check that nothing is covering part of the screen.

A misread shape can come from glare, blur, or a small glitch in the screenshot. Fix it by hand, then run the check again.

Hold off on the move until the board shown matches your actual game.

Seeing a suggested move laid out on the board can make a hard position easier to read.
